Preheat oven to 450.
Roll your pie crust into large 17"x12" triangle and place in a 15"x10" jelly roll pan and pinch down edges to make them scalloped.
Poke holes all over crust with fork to vent.
Bake for about 10-12 minutes or until golden, set aside to cool.
Once cooled make your ganache by placing your chocolate chips in a heat resistant bowl.
In Pyrex bowl or measuring cup pour your milk and microwave for about 3 minutes or until it starts to boil, pour over chocolate chips and cover for about 5-7 minutes.
Stir your chocolate and milk together until blended then pour over crust.
Refrigerate for about 15-20 minutes so the ganache can cool.
Meanwhile beat together your cream cheese, sugar and vanilla.
Fold in your whipped cream and mix until combined.
Add about 3/4 of your crumbled cookies to mixture and stir.
Spread onto your cooled ganache and then sprinkle with remaining cookies.
Refrigerate for about another 15-20 minutes to set up.
Cut and serve.
